Changeable exhibitor

ABSTRACT

THIS INVENTION REFERS TO A MULTIPLE PAGING APPARATUS WHICH EXHIBITS EXPRESSIONS CONTAINED IN A SERIES OF PLATES SUCCEEDING AUTOMATICALLY ONE BY ONE, TO BE READ OR OBSERVED, ACTIONED BY HAND OR MECHANIC MEANS, CHARACTERIZED BY A BOX CARRYING A WINDOW IN ITS FRONT AND ANOTHER WINDOW IN ITS REAR, THROUGH WHICH ARE SHOWING EXPRESSIONS MOUNTED OR PRINTED ON THE PLATES SUPPORTED AND CARRIED ALONG BY TWO SCREWS DISPOSED SIDE BY SIDE IN A HORIZONTAL PLANE AND PARALLEL TO EACH OTHER, AND ROTATING IN AN OPPOSITE DIRECTION UPON THE APPLICATION TO THE END OF ONE OF THEM OF A CIRCULAR MOVEMENT WHICH IS TRANSMITTED TO THE OTHER ONE BY MEANS OF A PAIR OF GEARS, CHARACTERIZED AS WELL BY VANES DISPOSED AT THE BEGINNING AND AT THE ENDING OF THE SCREWS THREADS, HAVING AS ITS PURPOSE, THOSE AT THE ENDING OF THE THREADS, TO ROTATE THE PLATES 180* ON ITS VERTICAL AXLE ABOUT THE HINGES JOINING THEM, BEING THE PURPOSE OF THE VANES FIXED ON THE SCREWS AT THE BEGINNING OF THEIR THREADS, TO ACCOMMODATE THEM IN A POSITION TO BE CARRIED ALONG BY THE SCREWS. THE TRANSPORT OF THE PLATES IS CONTINUOUS DURING THE APPLICATION OF THE MOVEMENT CAUSING THE SCREWS TO ROTATE.

Cl. 40-97 1 Claim ABSTRACT OF THE DISCLOSURE This invention refers to a multiple paging apparatus which exhibits expressions contained in a series of plates succeeding automatically one by one, to be read or observed, actioned by hand or mechanic means, characterized by a box carrying a window in its front and another window in its rear, through which are showing expressions mounted or printed on the plates supported and carried along by two screws disposed side by side in a horizontal plane and parallel to each other, and rotating in an opposite direction upon the application to the end of one of them of a circular movement which is transmitted to the other one by means of a pair of gears; characterized as well by vanes disposed at the beginning and at the ending of the screws threads, having as its purpose, those at the ending of the threads, to rotate the plates 180 on its vertical axle about the hinges joining them, being the purpose of the vanes fixed on the screws at the beginning of their threads, to accommodate them in a position to be carried along by the screws; The transport of the plates is continuous during the application of the movement causing the screws to rotate.

DETAILED DESCRIPTION OF THE DRAWING FIGURES The characteristic details of this multiple paging apparatus are clearly shown in the following description, and in the accompanying drawings which illustrate the former, same reference characters indicating alike parts throughout the several figures.

FIG. A is a front perspective view of the apparatus;

FIG. B is a front perspective view of the internal apparatus;

FIG. C is a front elevational view of FIG. B;

FIG. D is a top plan view of FIG. B;

FIG. E is a side view in elevation of FIG. B, and

FIG. F is an enlarged fragmentary view in perspective showing details of the reciprocal connection of the plates containing the expressions to be exhibited.

DETAILED DESCRIPTION OF THE INVENTION Referring now to the above mentioned figures, in FIG. A is shown a front perspective of the apparatus comprising a housing or box a, with a window b, through which plates are shown, these plates are to be fixed or printed with the graphical expressions which exhibition is desired. In its rear portion, the apparatus carries a window similar to the previous one and for the same purpose.

FIG. B shows the endless screws d, e, with helical pitches and rectangular threads, which rotate in a direction opposed to each other, applying in k a rotational movement by hand or mechanical means to the endless screw d, which is transmitted to or by means of gear 7, g. On the endless screws d, e, and resting against its 3,619,922 Patented Nov. 16, 1971 core, plates c are mounted one after the other, separated from each other by the thickness of the endless screw threads. At the beginning of helical thread in each screw, vanes i are fixed upon its core, and at the ending of the threads vanes h are fixed upon its core, the purpose of which will be hereinafter explained through the description of the apparatus performance.

FIGS. C, D, B respectively show a front View, a plan view and a side View of FIG. B, in which views are Seen all members of the apparatus in various positions.

FIG. F shows a conventional perspective of part of a group of plates 0, pointing out the way these plates are connected to each other by means of hinges n. The purpose of setting the hinges n in the form indicated is to make that the plates c, which are in positions to be observed by pairs through the front window b, stay in the same plane and assist to the rotation of the sample plates.

The operation of the apparatus is as follows:

With the plates being disposed one after the other, mounted on the cores of the screws d, e, separated from each other by a distance equal to the thickness of the screw threads, and in a number suflicient to cover its entire length, a circular movement is applied to k, in the direction indicated by the arrows in FIG. B. The plates on the screw d will be advanced toward the front of the apparatus, and those of the screw e will be advanced in the opposite direction. Upon leaving the coil of screw d, plates 0 will be suddenly precipitated one by one by the vane h, making them rotate on the hinges n, and in this new position they will be rerailed, one by one as well, by the vane i, in order to be left mounted on the core of the screw e, and to enter into the thread of this, which will drag them until the ending of this thread, wherein there is the other vane h which drives them in the same manner as vane h of the screw d, bringing them about in such a position that vane i of screw d return them back on the core of the latter to be transported by its thread, and to reinitiate their travel which will be interrupted until the application of the circular movement of k will cease.

If it is desirable to have a wider exhibition surface, without increasing the width of plates 0, it will be necessary one or various pairs of screws with their respective plates same as those described and connected to each other by gears such as f and g.

We claim:
